Is it possible within pl/pgsql, to convert an integer to an interval in
months? IE, if num_months is an INT set to 48, can it be converted to an
interval?
Thanks,
Brian

You should be able to say something like
num_months * INTERVAL '1 month'
I believe.

Can you use num_months * '1 month'::interval ?

select (1||' months')::interval;
You should be able to replace the "1" with your integer variable.

Sure, just multiply by the appropriate interval value:
regression=# select 48 * '1 month'::interval;
?column?
----------
4 years
(1 row)
